Not clients, but local names I've heard in the past...Harry Toole, Uneda Peter (why she married a guy with that last name is beyond me) and a Catholic Priest named Father Firmis Dick (forgive me if I misspelled any of these).

Here's the name of a girl that was in my class. Her name is Jenn Fell. Her boyfriends name was Eric M. Down. If they got married and she kept her last name and added his....Jenn Fell Down. Not a joke, these was really their names.
